Robert Smith isn't very masculine, but he is very straight. His love songs are overwhelmingly heterosexual...and dedicated to his hot babe wife, Mary.
Some gay-friendly musicians include:
Ani DiFranco (whom I adore--she's in a straight marriage, but has a bisexual past)
Consolidated (they're straight, but they defend gay rights)
Rage against the Machine (again, straight but defend gay rights)
Nirvana (CD liner note curse out homophobes and urge anti-gay bigots not to buy their music)
I don't think George Michael is bragging about his homosexuality in fact it took him a while to admit it (Boy George had an argument with him on that).
BTW do you remember when Elton John and Eminem had a performance together at the Grammys 2 years ago ?
A couple of anti-gay singers: DMX Snoop (hell, almost any rapper type)
There was a thread here a few months ago that discussed the "hard" gay black scene in NYC. Guys would go to gay black parties and get down to some anti faggot tunes.
You are talking about Fem to Fem. My good friend from High school was in that band just saw her at our 20th ruinion she said she is not gay though it was just a marketing ploy on her part. And she isn't lying she is married to a dude.
